Ibis and Bosherston

I waited from 08:00 to 08:45 at the bottom of Radford Pill, behind the Milford Brewery pub this morning but no sign of the Ibis. Another guy I met later had also been looking in the same area but saw nothing. Could be the birds took a slightly different flightpath or have changed feeding ground. However, it was -6.5 degrees at Milton this morning and the ground was/is solid. How do they feed and have they moved on? It will be interesting to see if they fly in again over Carew Cheriton this evening.
Late morning at Bosherston little of the lakes were frozen over. Pretty quiet there with 22 Goosander and 12 Goldeneye the highlights.
